摘要
本次设计对短应力线750轧机压下部分进行了相应的设计与校核。然后，轧机的两种轧制力计算方法进行了设计比较。本轧机为为二辊卧式轧机。本设计采用直流电动机，有较大的过载能力，电动机与轧机之间有减速器。压下装置动力部分采用液压马达，传动平稳，能在较大范围内实现无级调速，能保证较高的轧制精确度。最后对轧机的润滑和维护做了简单讨论。
本次设计主要的研究方法是根据轧辊孔型和轧制速度，计算轧制力，从而对轧辊进行强度和刚度的校核，确定轧辊是可用的，从而保证轧机能正常工作。在对轧辊轴承的选取，立柱的校核，压下装置的形式进行了研究，保证设计了的准确性。

Abstract
The design of the short stress line 750 Rolling Mill for the corresponding parts of the design and checking. Then, the two rolling mill was designed force calculation comparison. The horizontal two-roll mill to the mill. This design uses a DC motor, a large overload capacity, between the motor and reducer mill. Dynamic part of the reduction device with hydraulic motor, drive smoothly, can realize stepless speed regulation in a large range, can ensure a high rolling accuracy. Finally, lubrication and maintenance of mill made a brief discussion.
The main research design is based roll pass and rolling speed, rolling force calculation, and thus the strength and stiffness of roll of the check, to determine roll is available, thus ensuring mill can work. In the selection of roller bearings, columns of check, pressure device in the form of a study designed to ensure the accuracy.
Key words: 750 rolling mill; two roll mill; pressure equipment; oil motors; rolling force
